P3D A new RBT mount size

[Jon Golden / 3D Concepts <3dman@xxxxxxxxxxx>]

Here is a lively topic for discussion.  

1) I am gathering information for my trip to ISU, with the possibility of designing another aperture opening for RBT mounts.  If consensus says so...and the right info gets to me....RBT will consider designing another RBT mount between the Realist RBT5 23 x 21mm size, and the Ultra close-up RBT4  21 x 16mm size.

Based upon the history of  options that used to be available.
What would people like to see that one size be?

2) I am also lobbying for the design and implimentation of a masking system for all sizes of RBT mounts that will provide horizontal, vertical adjustments, and possibly a variety of unique shapes in circles, rectangles, triangles etc.  This would be a precision , ultra thin material,  that sits between two RBT halves, that is easy to use and adjustable.  Many of you have seen how I use half of an old EMDE foil to custom mask problem and special alighment requirement images ...well that is the concept here.Themelis 

Let the discussion begin (or not!)
